Does a shock push the axle down?

Once the spring length is exceeded, regardless of the shock length or shocker being used, there is no more downforce other than gravity.

Did you get in to work late today? Where ya been?

Been dealing with salesman speak all morning, people trying to sell things as salesman, rather than on technical knowledge.

So after dealing with them, I thought I better log on here, while I was on a roll :flipoff2:

I don't think you understood my explanation. Because the weight of the vehicle is on the inside of the tire that is being compressed some of that weight is transfered to the other tire. I'm sure you've seen pics where the low side spring is loose because of using long shocks, it's this force that is pushing down the axle on that side.

Still not the shock doing it. Yes the longer shock lets the axle hang farther down, but the purpose of this thread is to dispute the fact that emulsion shocks can push an alxe down.

The answer to that is no.

I'm not saying the shock was doing it but rather explaining what Shotts was seeing and that it was more than gravity.

Leverage is what your talking about, which could be easily calculated by the distance from tyre to spring on compressed side, which is deminished by the length its able to exert right across the housing to the wheel on the other side.

But its still a variable, as it cant be the same every time, if at all, so easier to have the right spring ;)
 
I realise there are other facters in this like the amount of bind in the system.

I came upon this thread accidentally and saw Shotts taking some shots so I thought I'd try and help others understand what he was having trouble explaining.

Rick...Rick...forget it. You won't win despite your vast knowledge on these issues. I know what your saying...you're pointing out one advantage a live axle has over an independant.

In other threads, other members tell me the same thing you are saying here about a front live axle vs IFS. The live axle acts as a lever as it rotates around the d-shaft and therfore more pressure is put on the drooping front wheel because of the pressure and weight on the stuffed wheel. IFS doesn't do that so you get less traction with IFS. Yada yada yada. Whatever.

Now, on this thread, people discredit that live axle advantage you mention. They're all hung up on springs and shocks. I don't give a rats rear what made the improvement. :)

Run that by me again? :D What does the driveshaft have to do with the leverage point of a solid axle?

This thread was about the possibility of a shock pushing the axle down.

It was not about the merits of installing a longer shock.

It was not about your seat of the pants feeling.

It was purely about a comment you made in a post that I wanted to show was not correct so that people that read it will not get the wrong idea.

There is no reason to cloud this over.

Maybe I should have made the title a question, maybe I should just have said

" A REGULAR SHOCK CAN AND DOES NOT PUSH AN AXLE DOWN"

Adding the N74L shocks helps this "problem" as the added rear pressure on the rear wheel when flexed helped to put added pressure on the opposing front. This helped F&R in the articulation dept.

You luv messing around with semantics. You know what Rick and I are both saying. And you know as well as me that my truck's off-road capabilites are improved just like they are on an 80 with the L's.

Quit foruming and ship out those front arms. My eyeballs are buzzing from being in that Lexus. :D
 
John, I did read it. The problem is that you make statements which are not correct. It is not a simple matter of semantics.

The axle does excert some leverage, but that happens around the link points. It has nothing to do with the driveshaft. So why is it wrong to point out that these statements are not correct.

Yes, I am picking on you. Why do you ask. You have your truck in a number of magazines, you have a site detailing mods etc, etc. So by default, newbies read these things and say, " Hey, look at what John has done with his truck, therefore what he says must be correct" however some statements you make are just not correct. Someone has to point this out.

If you have problems expressing what you are trying to say, consult with someone and then post. Don't just post statements about technical issues and think we are going to let them slide.

1. The live axle exerts some leverage (in different words. Rick's were better).

2. The N74L mod makes a notable difference off-road (why or how doesn't matter. It does, and you experts can better explain why than me, so go for it.)

You can pick on me all you want. :D

Tell you what....I'll put a disclaimer for you and the newbies on my website, and in my signature. It'll say:

"I've had some great ideas for vehicle modifications and some have turned out with excellent results. For the technical reasons why they worked, ask someone else."

Does that help to protect the newbies? :D

Ad that to your signature too and we will stop picking on you.......
